Ch. Fries gives an original classification of types of sentences. All the utterances are divided by him into Communicative and Non-communicative.
The Communicative utterances are in their turn divided into 3 groups:
I. Utterances regularly eliciting “oral” responses only: greetings, calls, questions.
II. Utterances regularly eliciting "action" responses, sometimes accompanied by one of a limited list of oral responses: requests or commands.
III. Utterances regularly eliciting conventional signals of attention to continuous discourse statements.
L.Barkhudarov compares source (kernel) sentences with their transforms, he distinguishes several types of sentences from their structural view-point. His classification will represent binary oppositions where the unmarked member is the source kernel sentence and marked one is the transformed sentence.
The most important oppositions within the limits of simple sentences are the following two:
1. Imperative (request) and non-imperative sentences.
2. Elliptical and non-elliptical sentences.
Summarizing the issue about the classification of sentences in the English language, we can say that this can be done from different points of view. But the most important criteria so are as follows:
1. The criterion of the structure of sentences.
2. The criterion of the aim of the speaker.
3. The criterion of the existence of all parts of the sentence.
From the point of view of the first criterion, sentences fall under two subtypes: simple and composite.The difference between them is in the fact that simple sentences have one primary predication in their structure while composite ones have more than one.
According to the criterion of the aim of the speaker, sentences fall under declarative, interrogative, imperative and exclamatory.
From the point of view of the existence of all parts of the sentence, we differentiate elliptical and non-elliptical sentences.
Generally, in all three compared languages sentences may be classified according to:

• 
  types of communication
  
• 
  structure.
  

According to the types of communication sentences in compared languages are divided into:

• 
  declarative,
  
• 
  interrogative
  
• 
  imperative.
  

A Declarative sentence states a fact in the affirmative or negative form. There are a number of differences between English and Russian, Uzbek negative sentences. An English sentence may have only one negation while the Russian sentence may have more than one. (Nobody was late. – Никто не опоздал.- Ҳеч ким кеч қолмади).Similarly, there can be observed a list of the ways of expressing negation in all three compared languages:
